Rail Profile
The rail profile is the cross sectional shape of a Track (rail transport), railway rail, perpendicular to its length. Early rails were made of wood, cast iron or wrought iron. All modern rails are hot rolled steel with a cross section Profile (engineering), (profile) approximate to an I-beam, but asymmetric about a horizontal axis (however see #Grooved rail, grooved rail below). The head is profiled to resist wear and to give a good ride, and the foot profiled to suit the fixing system. Unlike some other uses of iron and steel, railway rails are subject to very high stresses and are made of very high quality steel. It took many decades to improve the quality of the materials, including the change from iron to steel. Minor flaws in the steel that may pose no problems in other applications can lead to broken rails and dangerous derailments when used on railway tracks. By and large, the heavier the rails and the rest of the track work, the heavier and faster the trains these ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
